PROBLEM TO BE SOLVED: To provide a tire position registration system which can early finish the determination of a tire position.SOLUTION: When a tire 2 slips during traveling, the rotation of only the slipped wheel suddenly becomes high compared with other non-slipped wheels. That is, only the axle rotation information of the slipped wheel out of four pieces of the wheels is largely changed. Furthermore, a gravity center sampling cycle of the slipped wheel is abruptly changed to a shorter cycle Tr2 from a cycle which is taken at a normal time after a start of the slip. In another case, a change amount Fk of a centrifugal force which is generated at a tire valve 4 is largely changed by the slip. By confirming which axle rotation information of the four wheels is synchronized with the gravity center sampling cycle taken by the slipped wheel, and the centrifugal force generated at the tire valve 4 by utilizing a principle of the change, a tire position of only the slipped wheel is designated prior to the other wheels.

    【課題】タイヤ位置の判定を早期に完了することができるタイヤ位置登録システムを提供する。【解決手段】走行中にタイヤ2がスリップすると、スリップ輪のみ他の非スリップ輪に比較して突然回転が速くなる。すなわち、4本の車軸のうち、スリップ輪の車軸回転情報のみ大きく変化する。また、スリップ輪の重力サンプリングの周期は、通常時にとっていた周期から、スリップ開始後、急に短い周期Tr2に変化する。あるいは、タイヤバルブ4に発生する遠心力の変化量Fkは、スリップにより大きく変化する。この原理を利用し、スリップ輪がとる重力サンプリング周期や、タイヤバルブ4に発生する発生する遠心力が、4輪のどの車軸回転情報と同期するのかを確認することにより、スリップ輪のみ先にタイヤ位置を確定する。【選択図】図9
